Shanghai Hua Hong baghouse denier large selection of high quality polyester fiber yarns, with advanced equipment production of polyester (polyester) fiber needle punched filter felt, can be a variety of quantitative fiber evenly mixed, then multiple units and cotton mixed open carding unit favor different composite fiber layer mounted between the webs, gradient transformation. The product is in addition to a general class of cloth felt peculiar gap and high permeability, high dust collection efficiency, long life and other advantages, its moderate temperature levels, instantly reach 150 ℃, moderate acid, alkali resistant distinguishing features but also has a very good abrasion resistance, so it is a breed felt kind of filter to use large.
